and one more thing i forget to mention that in exam many students fails to present properly so you have to give a better presentation of answer. because lots of students fails not because they don't know the answer but they fails to present the answer properly in the exam.. because it is professional exam so your answer should also be like a professional so you should present your answer like a professional.. for example in company law : you should write first the relevant section number and the act and releated provison and case law also.. and your answer should be point to point instead of big paragraph it should be divided into small line with bullets..
for all this you can refer your institue suggested answer of compiler and present your answer in exam according to it...best of luck
